Comment 2 for bug 1973041

Refreshed version of the same thing, with the merge fixed, adding Replaces/Breaks fields due to the Ubuntu/Debian divergence on which package ships the new static libraries.

I used the dh-exec mechanism for the i386 exception as it is what is used in the current Salsa 13 branch for their grpc-unable architectures, thus it'll eventually reduce the delta.

The .insn patch has been forwarded to Debian: https://salsa.debian.org/pkg-llvm-team/llvm-toolchain/-/merge_requests/89
